Variable multiple wavelength

The Smartline UV/VIS detector 2550 combines the advantages of a spectro-photometer (such as high spectral resolution, high sensitivity and low drift values) with a high speed scanning technology for the simultaneous measurement of up to 4 channels. With a remarkable linear range, simultaneous determination of main analytes and impurities can be carried out without re-calibration. The 2550 comes with an installed deuterium lamp which covers a wavelength range from 190 to 750 nm. This detector can be controlled with OpenLab® EZChrom, ChromGate® and ClarityChrom® software, as well as from the front panel (stand-alone operation), via LAN, via RS-232, or through analog input/output; allowing it to be integrated into almost any LC system. Due to a smart design the flow cell is easily accessible and can be changed very quickly. You can choose between a wide range of flow cells for analytical or preparative LC applications with flow rates from 10 μl/min up to 10 l/min.
